Description
Tokina created the 1.6x Expander so that cinematographers can use their favorite Super35 PL lenses on the latest full-frame 6K/8K cameras. The Expander increases the diameter of image circle by 1.6x on Super35 PL prime and zoom lenses. This allows for a greater variety of lens choices when filming with cameras like the RED Dragon that has a 46.31mm (8K) diagonal sensor.
Tokina engineers gave special attention to the 7-element optical design to ensure the integrity of the original lens’ performance and to keep light fall off to a manageable 1.36 stops. The all mechanical design is robust, durable, and lightweight.
The Tokina 1.6x Expander performs best when used with lenses that have a T2.0 or larger aperture and when the lens is stopped down to T2.8 or smaller.
